Model/identifying # anti-glare screen?

Did a site-wide search, can't find a thread that mentions how one determines what model #'s, identification system; lets you know which MBP have an anti-glare screen in them.

Looking @ebay sellers for used 17"MBPs, many don't list whether or not (must assume glossy) it's an AG screen model...frustrating! (some of those dumbarse sellers won't even allow you to contact them to ask the Q---lose a sale).

...thought about it, then decided the risk with $650-700 price dif btw (many include ApplCare) the ave low ebay selling price was too great to go with Apple reefers. If Apple would drop the price another $300 (yeah right) I'd consider it.
